HUMIDIFIER.

Specification of Letters Patent.

Patented July 7, 1908. Serial No. 390,269.

To all whom it may concern:

Be it known that I, HENRY CLAUDE TowN- sEND', a citizen of the United States, and a resident of Anderson, in the county of An derson and State of South Carolina, have invented certain new and useful Im rovements in Humidifiers, of which the fol owing is a specification.

This invention is an improvement in humidifiers, such for instance as are used in cotton factories for moistening the air; and the invention consists in certain novel constructions and combinations of parts as will be hereinafter described and claimed.

In the drawing Figure 1 is a vertical section of an apparatus embodyin my invention. Fig. 2 is a detail longitu inal section of the cover tube.

Fig). 3 illustrates in lon 1 tudmal section and. ottom plan viewt e contr'ollin valve.

Fig. 4 is a sectional View of the air ue. Fig. 5 is a cross-section thereof on about line 5-5 of Fi .4, and Fig. 6 is a cross-sectional view on a out line 66 of Fig. 4.

In the construction shown the humidifier comprises a tank A having an inlet through which water may be supplied from any suitable source of supply, and a float valve or other controlling means may be provided for maintaining the water in the tank A at any predetermined level. The tank A A through which the cover tube present y described projects, and the bottom of the tank A is l providedwith an opening A through which the nipple B at the bottom of the air flue B projects, as shown in Fig. 1. The air flue B is pro 'ded with a base plate B which rests upon the bottom of the tank A, and the nipple B projects below the base plate B and is threaded externally and a nut B turned on the ni ple B up against the bottom of the tank forms a securing means for holding the air flue firmly in position in connection with the tank. Air may be supplied under any degree of compression by suitable connections with the nipple B from any suitable so'urce of su ply and passes upwardly in the operation 0 the humidifier and discharges from the air flue at the upper end thereof where a seat B. is provided for seating the valve presently described.

The air flue B is provided on its outer side with spacing projections B, which properly space the cover tube C away from the air flue, and these spacing projections B are channeled at B for the passage of water upwardly in the space between the air flue and the cover tube in the operation of the invention.

The air flue B is threaded internally at B and the controlling valve D has its valve proper D arranged to seat against the seat B and is also provided with the depending portion D having'at its lower end a plug 3 threaded within the air flue and channeled at D to permit the passage of air past the said plug in the operation of the invention. By this construction the valve D can be adjusted toward and from its seat to regulate the discharge of air, as will be understood from Fig. 1 of the drawing.

The valve D, has at its upper end a handle D with laterally projecting portions D which are notched in their lower edges at D to receive the sharp edge produced at the upper end of the cover tube C in raising the said cover tube so the handle will strike at D against the outer side of the cover tube C before the knife edge thereof abuts the handle portion, thus limiting the upward movement of the cover tube without injuring the spraying edge thereof.

The cover tube C rests at its lower end upon the base plate B of the cover tube and flts over the air flue B and around the spacing projections B thereon and this cover tube has openings C shown at its lower end for the assage of water from the tank into the s .ace between the cover tube and the air flue, w iich wardly in said space and water may pass u 1e form of spray, as indibe discharged in t cated in Fig. 1.

At its upper end the cover tube is deflected inwardly at C and its knife edge C rests com aratively close to the upper end of the air ue B, a narrow annular spraying space bein provided between the said arts, as will e understood from Fig. 1 of tie drawing. This provision of a narrow annular spraying space brings the air in contact with t e Water in a thin sheet, as distinguished from a pin point and this is important in 0bviating the clogging of the spraying discharge by lint and the like and a so facilitates the clearing or dis lacing of any accumulated lint by simply ifting the cover tube in the operation more fully described hereinafter.

The cover tube it will be noticed operates as a means for subjecting a limited quantity of water in the blast through the flue B and in operation the valve D may be adjusted to regulate the amount of moisture to be discharged into a 5 room as the more air applied the greater the amount of spray discharged, the discharging air tending to produce a vacuum at the spraying space and draw the water up to discharge the same in the form of spray in the operation of the invention.

The cover A serves to keep lint, dust and the like out of the tank.

As shown the cover tube C may be moved longitudinally upward from the position shown in Fig. 1, which is important as by raising the said cover tube above the spraying position shown in Fig. 1, the opening between said tube and the air, flue will be so large that the air from the air flue will blow out all trash or lint and this lifting of the cover tube is all that is necessary to clean the humidifier shown while with the devices for this urpose in common use it is necessary to ick int out with small pins or other suitable evices.

The construction is simple, easily operated, can be cheaply made, ossesses no parts apt to get out of order and will efficiently serve the purpose for which it is'designed.

What I claim is:

an opening in its bottom, an air flue having a base plate and a nipple below the same and projecting through the opening in the bottom of the tank, securing means on said nipple below the tank, the air flue being provided above its base plate with projecting portions channeled for'the passage of water and adapted to form. a spacing device for the cover tube, a cover tube fitted over the air flue'and over the spacing projections thereof and resting at its lower end on the base plate of the air flue and spaced at its upper end from the upper end of the air flue forming a spraying space, and a valve controlling said space and held adjustably within the air flue, openings being afforded for admission of water to the cover tube.

2. A humidifier comprising an air flue having internal threads, a cover tube over the air flue, a spraying space being provided between the air flue and the cover tube at the discharge end of the latter, and a valve having a'valve proper controlling the discharge of air and a depending stem having a threaded plug screwing into the internal threads of the air flue, and channeled for the passage of air.

' 3. A humidifier having an air flue provided at its outer side with spacing projections channeled for'the passage of water, a cover tube over the air flue and spaced apart there from by the channeled projections of the air flue, and a spraying space being provided between the' a r flue and the cover tube at the tank to the action of the air 1.
